You can't record the incoming backing tracks/song unless you connect them to the Pod's processing inputs. The Pod only sends its own sounds to your computer for recording. It does not send its incoming usb stream nor the input from its cd/mp3 player.

You might be able to run a 'Y' cable from the XT's headphone jack (1 male, 2 female). Use one for the headphones the other for running a line in to your sound card. You will have to figure out the level volumes on your DAW. You could probably just solder the cables together yourself to save a few $.
